Solid-state imaging device, signal processing method thereof, and image capturing apparatus

摘要

A solid-state imaging device includes a color filter array based on a checkered pattern array and in which two pixels adjacent to each other in at least one of upper/lower and right/left directions have the same color. The color filter array is a color filter array in which a spatial sampling point (x, y) is approximately arranged in at least one of (x=3*(2n−1+oe)+1±2 and y=3m−2 (n and m are an integer, oe has a value of 0 when m is an odd number and 1 when m is an even number)) and (x=3*(2n−1+oe)+1 and y=3m−2±2 (n and m denote an integer, and oe has a value of 0 when m is an odd number and 1 when m is an even number)).

主权项

1. A solid-state imaging device comprising:
a plurality of pixels; and a color array filter with filters over the plurality of pixels, the color array filter having a spatial sampling point (x, y) that is approximately arranged such that at least one of (x=3*(2n−1+oe)+1±2 and y=3m−2) and (x=3*(2n−1+oe)+1 and y=3m−2±2) is satisfied in which n and m are integers, oe has a value of 0 when m is an odd number and 1 when n is an even number, wherein,
the color filters are WRGB coded in a checkered pattern that is rotated by 45 degrees such that four adjacent pixels in up-down and left-right directions are in a checkered pattern with each pixel being of a color different than those of the other pixels, andW indicates a white, R indicates red, G indicates green and B indicates blue.
